The pro-drop parameter, or null subject parameter, is the parameter that determines whether or not a language is pro-drop. A positive setting of the parameter allows an empty pro-element to be identified by its governor, which is the case in pro-drop languages.
The analysis highlights Overview, Related Topics and Entities as prominent areas in the source structure around Null subject parameter.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
